Rear Disc Conversion

I am seeking information on how to use Ford and GM parts to put disc brakes on myDana 44 in my cj5. If anyone has specifics please respond. Some suggest the use of Ford front calipers and backing plate from late model Ford 2 wheel Dr. truck. I am told that this approach can save $4oo. over the purchase of a kit.

Re: Rear Disc Conversion

i'm sorry i guess i should have looked at the title. well i run a scout dana 44 front in my jeep and i had a spare so i just used the disc brakes from the front to build my own rear disc setup. i pressed the hubs out of the rotors and then i turned the wheel flange on the axles shafts so that the calipers would fit over the ends. then i took both caliper mounting brackets and cut half of the circle off of them that is formed by the hole where the spindle rides. i then used a hand grinder and ground out the half moon shape that was left on the mounting bracket so that it would fit around the outboard ends of the axle tubes. makeing sure that it was groung down enough that the caliper and pads would ride correctly on the discs. then i welded the brackets to the outer ends of the tubes and bought new calipers, brake lines, pads, and wheel studs. the thing to remember is that if you use this type of caliper bracket that when you move them to the rear you need to reverse sides from where they were in the front. i use scout front calipers so i don't have e-brake cables. i bought a mico leverlock to handle e-brake duties. i hope this helps. if you have any q's let me know.

Re: Rear Disc Conversion

I asked the same question and LukeJeeper sent me this E-mail, which I've saved:I went to the local speed shop and got weld on brackets for GM Intermediate calipers, I used rotors from a Blazer (6 lug) and calipers from a 78 Blazer. I got the rotors and calipers from AutoZone for $80 total and the brackets for $18. Do not use any caliper with parking brake provisions!!! They cost a buttload of money up front. For a 5 or 8 lug conversion, just pick a vehicle (GMs cost the least) and go to AutoZone, NAPA, etc and ask to look at the rotors and calipers for that vehicle. Then imagine putting the rotor on the inboard side of the rear axle flange. IF it will work- also purchase the wheel studs for that vehicle. I used air pressure to hold the caliper shut while I welded the brackets onto the axle tubes- but that is just what worked best for me. With a little creativity- you could have disk brakes for about $100. Good luck, and let me know if you have other questions I can answer for you. Luke

Hope it helps

Re: Rear Disc Conversion

You can get lots of different caliper brackets (bolt on and weld on) here:

They also have lots of different useful fittings and hoses.

Re: Rear Disc Conversion

The Street Rod Manufacturing company offers several bolt on brackets to adapt GM front or rear calipers to the D44. They also sell custom drilled rotors, rebuilt calipers, and stainless steel hoses that go from the original brake fittings to the swapped in calipers. They are cheap too!

Re: Rear Disc Conversion

Do they have a webpage, and do they use parts you can find at a normal auto parts store?
